In our
initial conversations with Zalman representatives about the Reserator 1,
FrostyTech was informed that one of the original design intentions of the
Reserator 1 cooling system was that the units be stackable. This is why there
are four screw posts integrated into the fin structure of the large cooling
tower. These posts would on later revisions be left untapped, as it became
unfeasible for consumers to purchase two Reserator units for
stacking.

The cap saw a few design changes, including the
addition of this small badge.

At the next
event that FrostyTech met up with Zalman to view the companies products, it was
clear that many small changes had occurred with the Reserator 1's overall
design. The stacking idea had been retired, and the four screw posts left as is.
The threads on the cooling tower cap were coarser to make installation quicker
(less turning) and less problematic (no chance of crossed threads), an emblem
was embedded in the side of the cap and laser etching used to mark the product
specs up top.

Version two of the Reserator 1 water cooling
system. Quite a few small adjustments had been made since the original
prototype unit was unveiled.

The hoses for the reserator system were replaced
with a blue material of slightly larger diameter and better
kink-resistance. The water block design was also modified slightly.

A new pass-through extruded aluminum GPU block
briefly saw use with the Reserator 1, but would later be retired in favour
of better performing designs.

The first attempt at a flow meter for the
Reserator 1.

Among the
assortment of minor changes done to the Zalman Reserator 1 cooling system, a
flow meter was also added. The flowmeter shown above would later be revised once
again as some of the compression fittings used were prone to leaks if not
installed correctly by the end user.
